Abstract
An end interconnector for one or both ends of a lead body of an electrical lead for an implantable medical device. The interconnector has an insulative body having a receptacle at its first end for each of a plurality of wire filars from the lead body, and a receiver at its second end for each of a plurality of connection wires extending from the medical device, such as an electrode tip. The interconnector provides electrical connection between the plurality of wire filars and the plurality of connection wires.
Claims20
An end interconnector for attachment to a lead body of an electrical lead for an implantable medical device, the end interconnector configured to engage with one of the proximal end or the distal end of the lead body, the interconnector comprising:
- (a) a body having a surface, a first end and a second end, the body first end having a longitudinally spiraled receptacle for each of a plurality of wire filars from the lead body, and the body second end having a receiver for each of a plurality of connection wires extending the medical device;
- and
- (b) an electrical connection region, configured to provide electrical connection between the plurality of wire filars and the plurality of connection wires.
An electrical lead for an implantable medical device, the lead comprising:
- (a) a lead body comprising
- (i) a proximal end and a distal end;
- (ii) a plurality of electrically conductive wire filars extending from the proximal end to the distal end;
- (b) an end interconnector electrically engaged with one of the proximal end or the distal end of the lead body, the end interconnector comprising:
- (i) a body having a surface, a first end and a second end, the body first end having a longitudinally spiraled receptacle for each of a plurality of wire filars from the lead body, and the body second end having a receiver for each of a plurality of connection wires extending the medical device;
- and
- (ii) an electrical connection region, configured to provide electrical connection between the plurality of wire filars and the plurality of connection wires.
A method of assembling the electrical lead for an implantable medical device, comprising:
- providing a lead body having a plurality of wire filars extending from a distal end to a proximal end;
- providing an end interconnector comprising:
- (a) a body having a surface, a first end and a second end, the body first end having a longitudinally spiraled receptacles for receiving each of a plurality of wire filars from the lead body, and the body second end having a receiver for each of a plurality of connection wires extending the medical device;
- and
- (b) an electrical connection region, configured to provide electrical connection between the plurality of wire filars and the plurality of connection wires;
- placing the wire filars from either the distal end or the proximal end of the lead body into the longitudinally spiraled receptacles at the first end of the interconnector;
- and
- electrically connecting the wire filars to the electrical connection region.
